To WHoM 1r, MAY ooNoEnN;

Be it linown that I, AMALTHA E. THORN, of FleteheigMiami county, Ohio, have invented certain new and useful Improvement in @burns 5 and I do hereby declare-the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification.

M y invention relates to that class of churns in which butter is-produced by the-motion of the barrel or chamber containing the cream, and my improvement consists, in the first part, in an arrangement of mechanical devices whereby said churn-barrel is operated; whilst the second part oi" my improvement relates to a method yof producing a more thorough agitation of thecream in the barrel or chamber, and also for introducing air into the body of the cream. Inthe accompanying drawingsi Figure l is a longitudinal section of a 'churn embodying my improvements; and

Figure 2 represents a transverse section of the same taken atl the line a: x.. .l Y

A represents the bed-plate which supports the churn, and its operating mechanism; and said bed-plate may be elevated a suitable distance above the :door by means of the legs B B. The churn-barrel or chamber-consists of a rectangular vessel, C, mounted on rollers D D', which run upon the upper face of the bed-plate A; and the churn-barrel is confined to a rectilinear path on'said bed-plate by means of the guide-pins EE; but it' preferred, the rollers D D' may be omitted, and the churn-barrel may slide on railways FF', (see g. 2.) The churn-barrel is provided with a series of removable and perforated vertical partitions, G G G, which are placed in a position at right anglesto themotion of the cream, in order that they may oppose the cream as much as is necessary to give it the required agitation. 'Ihe partitions G are securedbetween the vertical cleats e c, which are attached to the sides of the churn-barrel, and the partitions can be readily withdrawnfrom said cleats rfor the purpose of cleaning, tcl The lid H enters rebates in the sides of the churn-barrel, and it -is held securely in positionby the longitudinal baton I, and button J, and the lid is providedl with a handle, 7L. K K" are tubes which pass through the lid H, and the upper end'of one or both of these tubes is furnished with a downwardly-opening valve, 7c, for the purpose of admitting air into the cream. The churn-barrel is operated by thefollowing devices: Rising vertically from the hed-plate, A is a standard, Il, which alfords journal-bearings for the driving-shaft m, to which is secured a spur-wheel, M, and a y-wheel, N, the latter being provided with a handle, n, by which the driving-shaft is rotated. A similar standard, O, has liournalled in it a shafap, whose inner end, is provided with a crank, P, whilst its outer end has secured to it apinion, R, which gears with the spur-wheel M. S is a pitman or connecting-rod, one end 'of which is secured to the churn-barrel at s, whilst its other end is attached to vthe propelling crank?, and itwill be perceived that the rotation of said crank imparts a reciprocating rectilinear motion to the churn-barrel. 'I is a plug inserted in one end or the churnbarrel, and which, being removed,

`permits the4 buttermilk to escape.. A strainer, U,0v er the plug orifice, prevents the escape of butter when the plug is withdrawn. l v

The operation of my improved churn is as follows: The cream is poured inte the churn-barrel' C, until it rises some distancefabove vthe lower ends ofthe tubes K K', or about three-fourths the entire depth of. the vessel; and the attendant then proceeds to operate the ,churnby turning theily-'wheel N with the handle n, and, as the spur-wheel M has a simultaneous movement with the'ly-wheel, it produces ar'apid rotary movement of the pinion R, shaft p, and cra-nk P. The rotation of the cra-nh P imparts a correspondingly rapidly reciprocating motion to the churn-barrel C, and the-.contact of the cream with the' sides and the ends of said' vessel, and also with the perforatedvpartitions G, causes such a thorough and complete agitation of the cream, that a superior quality of butter is produced in a few minutes, and with the least amount'of manual exertion. The How ofthe cream from one-end of the churn-barrel to the other, induces a current of air Ato pass down the tube K; and as the valve c prevents it returning up the same tube, the air is forced through the entire body of cream, thereby assisting in increasing the agitation, and it finally escapes through -the other tube K. A cheaper but inferior movfliication of mydevice can be constructed by at aching the handle rn to the shaft P, thus dispensing with the driving-shaft m, spur-wheel M, andpinion R. y

I'claim herein as new, and of my inventionv l. The churn-barrel or chamber C, provided with the vertical perforated partitions Gr, in combination with the bed-plate A, guide-pins E E', pitman S, crank P, shaft 79, and propelling handle u, or*l their mechanical equivalents, all arranged and operating substantially as herein described, and for the purpose specified. v

2. The air-valve or valves c, in the vtubes lIS'. K', or one of them, in the vdescribed combination with the elements of the preceding clause.

In testimony .of which invention I hereunto set my hand.
